iPhone/iPod touch: Gina listed JiWire's iPhone app as one of the most reliable ways to find free Wi-Fi anywhere with an iPhone. There's now a new version of JiWire's app that maps out your results and sorts out free and paid hotspots.

The nicest thing about JiWire's new app—listed as "Wi-Fi Finder," as opposed to "Free Wi-Fi Finder," both under the JiWire label in the App Store—is that it works offline. Smart move, that, considering the likelihood of an iPhone user trying to hunt down Wi-Fi not having a solid cellular connection. The newer app also filters Wi-Fi locations, on a map or in a list, by type of establishment (cafe, hotel, library, etc.) and cost.
